A pioneer in the field of radiology, Edith H. Quimby (1891-1982) helped develop diagnostic and therapeutic applications for X rays, radium, and radioactive isotopes when the science of radiology was still in its infancy. Her research in measuring the penetration of radiation enabled physicians to determine the exact dose needed with the fewest side effects.

In addition to her accomplishments in the field of radiology, Edith H. Quimby worked to protect those handling radioactive material from its harmful effects. While a radiology professor at Columbia University, she established a research laboratory to study the medical uses of radioactive isotopes, including their application in cancer diagnosis and treatments. In recognition of her contributions to the field, the Radiological Society of North America awarded her a gold medal for work which "placed every radiologist in her debt."

Quimby was born on July 10, 1891, in Rockford, Illinois, to Arthur S. Hinkley, an...
